tiller Boat: What It Is and How to Manage It

For many beginners, choosing the first floating unit is a real challenge.tiller boat what is it?", which reflects a lack of understanding of basic principles of small craft management, and in fact, it is not a separate classification of the hull of the boat, but a way of controlling the power plant, which is mounted on the transom. outboard with a tiller vomit.

The system is controlled directly by a vomit that protrudes from the lower unit (motor leg), a classic scheme familiar to anyone who has ever sailed a Soviet-made motorboat or a modern Kazanka. Roompile control It is considered easier to design and generally more reliable because it has fewer mechanical connections that could fail, which is why most low-power engines, up to 10-15 hp, are equipped with this type of control.

But don't think it's just a small power thing. outboard motorsVomit-controlled systems, although they are less common and are often used in specific tasks, such as trolling boats or as auxiliary engines. Understanding how this system works is critical for water safety, since vomit control has its own specifics that are different from car steering or steering boats.

Principle of operation and Construction of the tiller control

The main element of the system is itself tiller It's a lever that's rigidly attached to the turn mechanism of lower unit, and when you turn the vomit to the left, the whole engine turns with the screw, and the jet of water is thrown to the right, pushing the stern of the boat to the left and the nose to the right, and this may seem counterintuitive to a beginner who is used to the car, but after a few hours of practice, muscle memory takes its toll.

In modern motor models, such as Yamaha, Tohatsu or HondaThe vomiting is often combined with the handle of the gas, which allows you to control the speed and direction of movement with one hand at the same time, and inside the vomiting there are cables or thrusts that transmit force to the throttle of the carburettor or injector system. spring-holder, which allows you to release the handle without resetting, which is convenient when trolling or long movement in a straight line.

Technical specificity

Why is the vomiting long?: The length of the tiller vomiting is not a whim of designers, but a necessity dictated by physics. The longer the lever, the less effort it takes to turn a heavy lower unit on the go, especially if the propeller has a large pitch or is damaged by underwater objects.

It is important to note that many motors are Friction lock (friction lock) A special screw or lever at the base of the vomiting, which fixes its position relative to the lower unit, prevents the motor from spontaneously changing the angle of rotation under the influence of vibration or waves, which is especially important when driving against wind or current.

Differences between the steering control and the tiller control

The main difference lies in the ergonomics and distribution of tasks of the operator. steering-pattern The control is divided: the steering wheel is standing or sitting at the console, holding the steering wheel with both hands, and the gas controls with a separate lever (gas machine). In the tiller circuit, all functions are concentrated at one point, which imposes restrictions on comfort, but gives a gain in maneuverability and reaction speed.

In the case of a tiller control, the operator is often forced to stand or sit on a jar (seat-cross) with his back or side to the direction of travel, constantly looking back to see the trajectory. The rudder boat allows you to sit face-to-face as you go, which is much more convenient for navigation and view. tiller It benefits in saving space: the absence of a remote, steering cables and a console allows you to use the entire width of the cockpit for fishing or load placement.

There is also an intermediate option. remote-controlWhen you have a small remote control that you can take on board, through a cable or electronic system, to the vomit, but the classic tiller boat involves direct contact between the operator's hand and the engine's vomit.

Boat control technique on the tiller

Management skills cock-boat The tricky part is that to turn your nose in the right direction, you have to push the vomit in the opposite direction. If you have to turn the boat's nose to the left, you push the vomit to the right, and this inverse control often causes minor collisions at the berth of newcomers.

When you're moving along a wave, the rample requires constant attention, the wave can try to pull the vomit out of your hands or, conversely, sharply wrap the boat. Experienced boaters use the soft-arm technique, not clamping the vomit with a dead grip, but only correcting the course with light movements of the hand, which allows you to extinguish the jerks and maintain course stability.

The special attention is given to reversing, because the propeller pushes the boat rather than pulling it, the control becomes even more sensitive, and the sudden addition of gas in the back can cause the boat to turn sideways to wave, which can be dangerous. water-dragging Or even rollovers on small craft.

Compatibility of PVC boats and metals with tiller engines

The choice of housing for the tiller engine depends on the operating conditions. PVC Boats They're lightweight, can be pulled ashore and turned nose-to-water by hand, which makes up for the lack of reverse on some older motor models, and the soft sides of PVC boats are less critical to accidental impacts on a berth when maneuvering with a vomit-rump.

Metal Boats (e.g. Kazanka, Ob, Salute) are also often equipped with rumble motors, especially in the budget segment. However, here the question of translation arises. If the boat is long (more than 4 meters), then the control of the short vomit becomes physically difficult, as the lever of influence on the course increases. pulp-extensioner.

The rootle extender is a simple metal or plastic pipe that is worn on a regular handle, and it allows the operator to sit deeper in the cockpit, while maintaining control of the motor, and without the extension cord on the long boat, you would have to sit on the stern overhang itself, which is unsafe and uncomfortable.

Type of boat	Recommended motor power (hp)	Features of management	The need for an extension
PVC boat (2 seats)	2 - 5	High maneuverability, light weight	Not required
PVC boat (3-4 seats)	9.9 - 15	It needs attention on the wave.	Preferably.
Metal (up to 4 m)	5 - 9.9	Inertial, sailing	Often required
Metallic (over 4 m)	15+	Hard move, hard turn.	Sure.

Advantages and Disadvantages of the tiller Scheme

By understanding the subject “tiller boat what is it?The objective pros and cons of this configuration cannot be ignored. The absolute advantages are the simplicity of the design. There is practically nothing to break here: no hydraulics, no complex cable systems that can rust or burst. The maintenance is reduced to lubricating the hinges of the lower unit rotary mechanism.

The second plus is cost: a tiller-operated outboard motor is always cheaper than a remote-controlled one, with price differences of up to 30%, which is a crucial factor for many anglers’ budgets, and the tiller takes up less space in transport and storage.

But the disadvantages are also significant. Chief among them is operator fatigue. Keeping your hand on weight or strain for several hours of fishing is difficult. In addition, the tiller boat is less suitable for movement in fog or at night, because the operator is constantly distracted by controlling the position of the engine and can not fully focus on navigation.

⚠️ Attention: Never tie a tiller vomit with a rope to the side of a boat to fix the course! When a screw hits an underwater obstacle, the motor must be able to deflect (turn the recline system) so as not to break the lower unit or turn the boat over.

Choosing a motor for a tiller boat

When choosing an engine for your rod-boat Notice the presence of an emergency stopper system, which is a clip cable that attaches one end to the motor and the other end to the operator's clothes or wrist, and if you fall overboard or release the vomiting, the engine will instantly stall. For the tiller control, this is a critical option.

It is also worth considering the existence of a system. electronic ignitionOn older engines with magdinos and interrupters, the control of the gas was less accurate, the engine could stall on idle or, conversely, not develop full speed. Tohatsu M9.8 or Yamaha 9.9 provide a smooth set of thrust, which allows you to confidently drive the boat even in difficult conditions.

For heavy-duty applications, like in the Volga Delta or in the north, many people choose two-stroke engines, which are lighter than four-stroke engines, which is important for inflatable boats, and are easier to transport in any position. motors quieter and more economical, but heavier, which can shift the center of gravity of the boat and worsen driving performance.
